Which one would each critic pick
| Critic | Gemini Code Assist | Tabnine | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.8 | 5.3 | Gemini Code Assist — Pick it if your company already pays Google Cloud and lives in JetBrains or VS Code; pick GitHub Copilot if your code lives on GitHub, where the invoice is already approved. |
| El Crítico | 5.8 | 5.3 | Gemini Code Assist — Agent mode can change resources outside the IDE and the docs say there is no option to undo those changes; yolo mode removes the one prompt that would have stopped it. |
| El Profesor | 5.8 | 5.5 | Gemini Code Assist — Recitation and source citation are switched off in agent mode, so the one verification feature the completion path has is absent from the path that edits files. |
| La Inversora | 6.8 | 6.0 | Gemini Code Assist — Google shut the free individual tier on June 18, 2026 and pointed consumers at Antigravity, which makes this a Google Cloud line item, not a growth bet. |
| La Jefa | 6.3 | 6.5 | Tabnine — Air-gapped, on-prem, SSO, zero retention, IP indemnification and $59 a seat on annual terms; approved, with a clause about the new owner. |
| El Hacker | 3.8 | 5.3 | Tabnine — Closed source, no free tier, and I cannot even try it; but it runs on-prem, air-gapped, against an LLM I host, which is more than the open tools with a cloud habit can say. |
